The KSD1616A-Y is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads. Here is an image showing the pin diagram of this transistor.
Classification of hFE
The KSD1616A-Y transistor can have a current gain of 135 to 270. The gain of the KSD1616A will be in the range from 135 to 400, for the KSD1616A-G it will be in the range from 200 to 400.
Complementary PNP transistor
The complementary PNP transistor to the KSD1616A-Y is the KSB1116A-Y.
SMD Version of KSD1616A-Y transistor
The 2SD1615A (SOT-89) and 2SD1615A-GQ (SOT-89) is the SMD version of the KSD1616A-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
